Abstract

The existence of the wood needs to be considered so that the use of wood for a particular use needs to pay attention to the quality of wood, both for wood for building materials, furniture, panels, crafts and so on. The weakness of wood compared to substitutes such as metal and concrete is its hygroscopic nature. The aim of this study was to determinethe effect of wood parts treatment on axial direction and sticker thickness on natural drying time on changes in the physical properties of gerunggang wood (Cratoxylon arborescens Bl.). While the expected benefits are as information material for the wood processing industry and wood users to be able to dry the wood properly. The research was conducted at the Forest Products Technology Laboratory for 3 months. Cutting is done by dividing the length of the stem into 3 (three) equal parts in the axial position, namely the base (a1), middle (a2) and end (a3), each cut length ± 2 m for the board (example drying test) ) with ± 2 cm thick and ± 15 cm long for example test of moisture content, specific gravity and shrinkage. The results showed that the average value of fresh water content, saturated point moisture content, and air dry water content had a tendency to decrease in value from the base to the end of the stem. The natural dryingtime has an average tendency to dry more quickly from the base to the end of the stem, with drying times ranging from 28-40 days or an average of 33 days. The end of the wood with a thickness of 3,5 cm sticker dries faster (25 days) with a defect 1 broken edge. Parts of wood with a sticker thickness of 3,5 cm dries faster than the thickness of the stickers 2,5 cm and 1,5 cm. The results of measurements of (BJ) density of gerunggang wood averaged 0,55 including the medium group (BJ 0,4-0,6). Specific gravity has a tendency to increase in value from the base to the end of the rod with an uneven pattern including type 3. The tangential and radial direction shrinkage ratio of 1,88 is included in the medium classification, then gerunggang wood can be used for boards and lightweight construction under the roof, crates, furniture, plywood andconcrete molds. It is recommended to conduct further research on the possibility of using gerunggang wood for artificial boards.Keywords: drying, wood parts, physical properties, gerunggang.

Abstract

Tumih wood (Combretocarpus rotundatus (Miq.) Danser) is classified as an unknown type of wood which is widely grown in peat swamp forests in Central Kalimantan. This study aims to analyze the physical properties and mechanical properties of wood in axial and radial directions so that they can be utilized properly. The results of the study resulted in fresh water content and dry air content of wood air, each of which was 71,58% and 19,33%, kiln dry weight 0,72, tangential shrinkage 9,68%, radial shrinkage 5,02% and longitudinal shrinkage 0,19%. Testing of mechanical properties resulted in a flexural firmness of 618,33 kg/cm2, compressive strength parallel to the fiber 333,27kg/cm2, shear constancy 92,02 kg/cm2, hardness 355,60 kg/cm2, and stiffness at 19,50kg/cm2. Based on the Indonesian Wood Construction Regulations Standard (PKKI) NI 5-1961 tumih wood is included as a strong class III of Indonesian wood, so it is quite well used for home building raw materials, beams, floor and wall boards, door/window frames, and furniture.

Abstract

Central Kalimantan has many types of wood such as Rengas (gluta sp), Bangkirai (shorea laevifolia endert), and Agathis (agathis spp). The third type of woods are found in the company of furniture as a result of waste in powder form so that it can be utilized for the manufacture of charcoal briquettes. The purpose of the research is to find out the characteristics of charcoal briquettes from wood waste Rengas, Bangkirai, and Agathis which refers to the Indonesian National Standard (SNI 01-6235-2000). The treatment of this research done on Bangkirai wood, Rengas, and Agathis which have different density with 5 replications so that the samples obtained 15 pieces. Data analysis was conducted to determine the effect of the treatment on the character of the studied and if it has significant effect then it is analyzed test difference average middle value that is specified by Coefficient Value of Diversity. Charcoal briquettes testing generally meets Indonesian National Standard (01-6235-2000) on charcoal briquettes except for volatile substances. The research data finding from these three types of wood which examined showed that the type of Bangkirai wood powder has the best charcoal briquette quality because of lower water content is at 5.05%, the higher density is 0.72 g/cm3, the ash content is 1.9% , carbon bound is 63.30%, volatile substance content is 29.75%, press firmness is 41.67kg/cm2, and calorific value is 6958.94 kal/g

Abstract

Fuel oil and gas in the coming years will still be the main energy source in supporting community activities. However, the increase in world oil prices led to an increase in fuel prices including gas and kerosene. One of the alternative energy sources that can be used is the use of wood waste as fuel for households or industries in the form of biomass pellets (pellets). The purpose of this study was to determine the quality of wood pellets from laban wood (Vitex pubescens) based on SNI 8021: 2014. This study used laban wood powder from the stems, branches and twigs, and tapioca flour as adhesives. The size of the powder used was 40 mesh stuck in 60 mesh. The pellet stamping used a pressure of 60 kg/cm3. The wood pellets tested included moisture content, density, volatile matter content, fixed carbon content, ash content, and calorific value. The test results showed that the stems of laban wood pellets produced better qualities than the branches and twigs parts although they were not significantly different. The range of laban wood pellets from the middle stems, branches and twigs were 11.27 ̶ 11.62% (moisture content), density were 0.34 ̶ 0.53 g/cm3, ash content were 0.83 ̶ 1,05%, volatile matter content were 71.20-72.00%, carbon content were 14.93-16.38%, and calorific value were 4486.46 ̶ 4514.46 cal/g. The test results were within the requirement of the Standards of Indonesia (SNI 8021-2014), the Korea Standard (KFS), and the Jeman Standard (DIN51371), except the density was not within the requirement of the SNI 8021-2014 Standard and the Jerman Standard (DIN51371). The density of the stem section was within the requirement of the Korean standard.

Abstract

This study aimed to identify nest density and orangutan (Pongo pygmaeus wurmbii) population as well as nest characteristics (nest tree type, nest tree height, nest tree diameter, nest age class, nest location) in the special zone of the Peat Forest Nature Laboratory (LAHG) of Sebangau National Park, Central Kalimantan. The research used the strip transect method with the length of each line ± 1000 m and a width of 20 m on each right and left side of the line as many as 5 transect lines. The objects of observation were orangutans, orangutan nests, and nest trees along the transect lines. The results showed that the average density of orangutan nests in the LAHG special zone of Sebangau National Park in Central Kalimantan was 375.17 nests/km2 with an estimated orangutan population density of 0.987 individuals/km2. Characteristics of orangutan nests found in the research location include: the most common tree species used as a place to make orangutan nests is Tarantang (Campnosperma coriaceum (Jack) Hallier f.) from the Anacardiaceae family. The height and diameter of the most dominant trees used as orangutan nests ranged from 11-15 m and 11-20 cm, respectively. The height of orangutan nests from the ground ranged from 11-15 m, the class of nests included class B, and the position of nests included category 4.

Abstract

Wood or lignocellulosic materials with high extractives are not recommended for making cement boards. Extraction of raw materials before the cement board manufacturing is a treatment carried out to address this issue. The aim of this research is to determine the influence of cold and hot water extraction treatment on Bamban particles on the quality of the cement boards. This research was conducted by immersion bamban particles on hot water (boiling at 100°C) for 3 hours. The mixture ratio between cement and bamban particles was 1.5:1 (w/w), and it was compressed for 1 hour at a pressure of 30 bar, followed by manual pressure (clamping) for 24 hours. The physical and mechanical properties of cement boards was conducted according to SNI 03-2104-1991 for wood-wool cement boards. The results of the study show that hot water extraction treatment has a very significant effect on the quality of the resulting cement boards.
